Merc Flow Torque prop hub uses 3 washers and a self locking nut. The only one so far that isn't just a flat washer is the bevel (or conical) type. All dimensions are accurate except for maybe the Height. My caliper's jaw was not made so I could get to outer edge of each side. I should have layed...
This was my Dad's, it's a Sears Robuck and Co Craftsman 60, just 3 amps and 425 RPM. It takes a few seconds to spin up and a bit longer to stop. Watched my Dad drill something on the patio as a kid and then get spun a 1/2 revolution before he could let it go
Edit: not Craftsman
In general no
They look good, but there is a list of issues with the boat and have mentioned some of them prior. Even the deck gelcoat is poor, it has areas starting to show it's wearing through. My old 1994 Formula showed less wear than this one.
Replaced Rev4 with Mirage Plus props today. Took me a bit to figure out how to swap the Tor-flow HD hubs, but got it done.
Removed my props because I wanted to switch from the 19p Rev 4 to 21p Mirage plus hoping i could get some more reverse docking control.
Note: See pic on how the washers...
I love your country (had 2 days there in 1978) and have thought many times of moving there but geezers, but my current beer ration would be a mortgage payment
Not into but clean through with plate and bolt/nut the stringer. The bolts are horizontal and above the bilge deck, so no way for water to sit and work it's way in.
